I used the USCT kit and agree that the directions suck. I squared mine to the front torsion bars using triangulation. Before I started, my car had always had more outboard room on the pass side. When I was done squaring the boxes up, it was exactly the same way still. it actually gave me a level of confidence that I had them in there squarely. Im running a 30” tall tire (PBR 29.5x10.5) on a 15x10 / 5.5 bs wheel. I also had to move the axle rearward by nearly 1/2” to clear the front edge of the stock wheel opening. I achieved this by having USCT build my buckets with the mounting holes rearward by my specified dimension.
